The invention relates to a method for expanding the jawbone crest (1) so that it can receive a final dental implant (4) the expansion of the bone crest (1) being carried out using an expander implant that is a biocompatible and osteoconductive part with an expanding purpose. The use of the expander implant (3) to widen the bone crest (1) has an important effect in that said implant is used as a support for the bone thereby stimulating the consolidation of the fracture of the bone crest (1) and the formation of bone around said implant. For this reason the bone generated around the expander implant (3) is of high quality. The invention also relates to the optional correction of the angulation of the alveolus during the widening so that the final dental implant (4) and the corresponding dental prosthesis remain adequately oriented. The invention further relates to a specific expander implant design (3).
